Lightweight Java Game Library Code

Let otherwise generic AWT utilities classes take a Component instead of the more specific AWTGLCanvas

Windows: Moved Display.setIcon logic to java

Linux: Added alpha mask support to Display.setIcon

Removed 2D OpenGL initialization code from Display. It messes with the implicit, but well-defined, opengl default state and doesn't fit well with multiple context types (gl3 and d3d)

Added notes to Mouse.poll() and Keyboard.poll() that Display.processMessages() (or Display.update()) must be called to receive new input state

Added AWTInputAdapter.isCreated() requested by kevglass
